Bad Popcorn In Big Buckets

The research questions were clearly stated with both dependent (9 point Rickart scale questionnaire) and independent variables (large v average sized containers and stale v fresh popcorn) identified. Study was a randomly controlled trial, 2 x 2 between-subjects design.Participants were randomly given either a 120 gram or a 240 gram container of pre-weighed, fresh or stale popcorn to eat while viewing the movie; after the movie the containers and remaining popcorn were re-weighed to determine measures of consumption; participants were also required to complete a 9-point Rickart scale questionnaire in order to measure perceived taste and to write a description of the in order to measure palatability of the popcorn, and to write a description of this palatability and whether they considered the size of the containers as having any impact on the amount they consumed.Location: Philadelphian cinema – ‘Stargate’ movie. Subjects: 158 viewers of the movie, 57. 6% male; fre sh popcorn – average-sized containers: n=38 and larger-sized containers n=40, stale popcorn – average container: n=39 and large container, n=40; means and ANOVA results (analysis of variance) indicated that participants in each randomized sample were comparable in age (28. 9, 30. 4, 29. 0 and 27. 2 years of age, F=0. 465, P>0. 20), and gender mix (57%, 60%, 62%, 54% male, chi-square = 0.522, P>0. 20. Findings: regression coefficients show that those given fresh popcorn ate 45. 3% more from large containers (85. 6 vs 58. 9 grams, F1, 76=38. 6, P,0. 01) The size of container proved to have compelling influence on consumption, which was higher for both fresh and stale popcorn (45. 3% and 33. 6% respectively) when eaten from the large containers, even when regarded as unpalatable (disliked) by participants (50. 8 vs 38. 0 grams, F 1,77=8.73, P. 0. 01). Fresh popcorn however, procured a larger increase in consumption than the stale (F1, 154=7. 42, P
